Message not sending

[sukirtisharma26]

@app.route('/sendmsg') def sendmsg(): to = request.args.get('to') msg = request.args.get('msg') token = request.args.get('token') if(str(token) == expected_token): client = Client(login, password) res = client.send_message(to, msg)

In the above flaskapp.py file , res returns me "None" and no message is sent.
